Be it knownihat I, WILLLut 1. Senna,

,citiZen of the United States, residing at St.

Louis, State of hlissouri, have invented certain new and useful Improvements in Shoe- Crimpers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a par-thereof.

Q My. invention has relation to improvements in electrically-heated shoe-crimpers;'

and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a standard showing my invention bolted thereto; Fig. 2 is aside view of the crimper with parts broken away; Fig. 3 is a.

away; Fig. 4 is a longitudinal section on the line 4-4 of Fig. 3; and Fig. 5 is acrosssection on the line 5-5 of Fig. 2. i

- The present invention has for its object to provide an electrically-heated shoe-crimper or creaser, that is to say, for crimping shoe-uppers, in which the tei'nperature may be maintained as uniform as poss1ble,- this resultingin a product correspondingly uniform w'here as in the prevailing method,

a crimper is heated by a flame, the temperature of the device begins to drop the moment the flame is removed; and, as the heat can not be reta ned for any, COIlSZClGlilblB length of time, the uppers treated last are subjected to amuch lower temperature than thoseftreated'first, and hence the'product is not uniform.

The advantages of the invention will .be

clearly apparentfrom a detailed descrip- "tion thereof, which is as follows;

Referring to the drawings, S represents 1 f astandard to an arm A of which is'bolted "I'or otherwise "secured the crimper 1. The;

crimper. comprises a curved arm or member .1 of theform substantially as shown, the upper. face. of the free end' thereof .being' provided with a transversely ribbed iter- 'minal former die 2,' the ribsbeing parallel and serving to "impart the necessary impression or finish'to the front of the shoe upper,

the shoe H being passed over the form as well imderstood in the art, andthe ne cee-' sary impression made by a reciprocating plunger 3 operated by a pedal 4 through any convenient series of links or other mech:

Within this cavity is placedQ a heating coil C in the present form consist-f ing of wire wound around sheets of inica 121-, though I do not wishto be limited, to any particular construction of coil. The insu: lated ends of the wires leading from the" coil are led through'the groove 7 where'they;

the wires leading out of the groove to a'suit any suitable source of electrical energy,- not shown) may be accurately adjusted-topro; 'duce any desired temperature in the coil; The latter is protected, and held in position within the chamber 8 by a cover vplate:9 ,screwed to the member 1 opposite the wall I which carries the die a sheet (if-mica m insulating the plate from the coil. is readily seen that the temperature aitwhich. the die 2 should be maintained to make a' uniform impression on the leather of the so that a uniform product can be turned-out crimpsformed by the transverse ribs ofthe-; die leave a permanent ornament or impl es-2 serve-the purpose .ofreventing the starting f of theycracking of tie leatheriin walkin 9 the transverse grooving of theleather-a I ready corresponding to the positions wh ch the cracks would assume were the upper left nncriinped.
